Spray counter lightly with non-stick cooking spray.
Combine 4 rolls and roll into a 12-inch circle. Repeat with remaining 4 rolls. Cut both circles into 8 wedges. Overlap 3 pepperoni slices onto the wide end of each wedge.
Place one half of a cheese stick on top of the pepperoni. Starting at the wide end roll each wedge to point. Place point down on a sprayed baking sheet. Bake at 350°F 10-12 minutes or until golden brown.
While rolls are baking, combine melted butter, garlic powder, Italian seasoning and Parmesan cheese in a small bowl. Brush rolls with sauce while still warm. Serve with marinara or ranch sauce, if desired.
